  Messier object - Wikipedia, the free encyclopedia
The Messier objects are a set of astronomical objects catalogued by Charles Messier in his catalogue of Nebulae and Star Clusters first published in 1774.
The original motivation behind the catalogue was that Messier was a comet hunter, and was frustrated by objects which resembled but were not comets.
Because all of the Messier objects are visible with binoculars or small telescopes (under favorable conditions), they are popular viewing objects for amateur astronomers.

 Messier Club Introduction
There is a slight touch of irony in the fact that Messier's chief claim to immortality grew out of his efforts to rid himself of a nuisance to what, he felt, was his important life's work.
Since the purpose of the Messier Club is to familiarize the observer with the nature and location of the objects in the sky, the use of an automated telescope which finds the objects without effort on the part of the observer is not acceptable.
Also "Messier marathon" sessions where all the objects are found in one occasion is to be discouraged if the beginning observer depends on other experienced observers to find the object to be observed.

To count as a genuine photograph of a Messier object, images on standard 3.5 x 5-inch prints or on contact prints of the negative sheet had to be easily recognizable as being the Messier object claimed when compared to the photographs in the Messier Album by Mallas and Kreimer.
A field notebook was prepared containing a list of all the Messier objects, their size, type, and estimated magnitude, as well as their coordinates (2000).
The objects were initially found either by visual sighting through the telescope’s five-inch f/5 refractor finder, or by using the telescope’s large setting circles.

 Binocular Messier Club Introduction
The required information is: the name of the object; date and time of the observation; an estimate of the seeing and transparency; the size and power of the binoculars used; and perhaps, a brief comment on what you saw.
Tougher objects are small and dim in the field of view and require identifying the fields around them with the help of some sort of star chart to verify their location.
So, if you are wondering what is the best time of the year to observe a Messier object, refer to Appendix C. Appendix C tells you which season to observe each object, each object's coordinates, their NGC numbers, the constellation they are located in, and their sizes and magnitudes.

Messier objects are stellar objects, classified by astronomer Charles Messier in the 18th century, ranging from distant galaxies to star clusters to stellar nebula.
The first object in Messier's catalog, the Crab Nebula, is labelled M1.
One of the great pursuits for amateur astronomers is to do a Messier Marathon, trying to view all of the objects in Messier's catalog in one night.

 The Additional Messier Objects
In addition to the 103 objects which were included in the final published version of Charles Messier's catalog, he and his friend Pierre Méchain have discovered others during the time when they compiled this listing, or shortly (at most one year) later.
Messier seems to have seen them also on March 24, 1781 when he measured M97 and created the description - according to the text of the description, and his manuscript version where he has them preliminarily numbered "98" (M108) and "99" (M109) without positions.
Moreover, these objects are now wellknown by their "M" numbers, especially among amateurs, so that it seems appropriate to accept these additions.

Messier Objects Charles Messier (1730-1817) Published in 1781, Charles Messier, the French astronomer, made a list of 103 "fuzzy-looking" objects that might be mistaken for comets.
Charles Messier (1730-1817) Charles Messier, was a French Astronomer whose work on the discovery of comets led to the compilation of the Messier Catalogue of nebulae and star clusters.

Charles Messier was one of the best comet hunters of the 1700s, with 12 comet discoveries to his credit.
In a sense, the Messier objects are the testing grounds for budding skywatchers.
The first inkling that these non-stellar objects were a facinating collection of star clusters, gaseous nebulae, and galaxies was the work of Sir William Herschel, who was able to resolve many of these hazy and mysterious objects into clusters of stars.

 Messier Objects
Charles Messier was born June 26, 1730, and he devoted much of his life to the search for comets, which generally first appear as diffuse objects.
As he came across these objects, he would catalog them so that he could go back to these objects later to verify if they were in fact comets or some other object.
If the object had remained stationary within the stellar background, it was, Messier believed, a nebula or a tight cluster of stars.

 Messier Marathon Tips   (Site not responding. Last check: 2007-11-06)
You will eventually come to a point when you have observed all Messier objects which are currently observable for you, and have to wait that the morning objects rise; it is sometimes recommended to take this after the Virgo Cluster, M83, M68 and M102 (NGC 5866).
If you have decided to observe more and other deep sky objects, here is a list of objects from which you could select (also available with data).
These objects were selected because most of them should be observable even with smaller Messier Marathon equipment, are situated in the neighborhood of Messier objects, or are of particular interest due to some reason.

Nicknamed the “Comet Ferret” by France’s Louis XV, astronomer Charles Messier (1730-1817) charted the positions of certain celestial objects that he felt could be mistaken for comets.
It is possible that his initial motivation for documenting the positions of “comet-like” objects evolved to a desire to catalog a broader repertoire of nebulas and clusterings for their own sake.
The irony of Messier’s enduring legacy is that his aim, at least initially, was to steer observers away from these now famous treasures.

It was one of the first major milestones in the history of the discovery of Deep Sky objects, as it was the first more comprehensive and more reliable list: Only four objects were initially missing because of data reduction errors, which could be figured out later though.
The study of these objects by astronomers has led, and continues to lead, to important, incredible discoveries such as the life cycles of stars, the reality of galaxies as separate 'island universes,' and the possible age of the universe.
While Messier's catalog was the first major reliable collection of deep-sky showpieces, and without doubt the most famous and important, others have followed since, including similar collections suitable e.g.

These images were used for Sky and Telescope's Messier Objects in Color Poster.
Because the images have the same relative exposures for each object type and the same camera orientation and image size, they can be used to compare one Messier object with another.

These objects were discovered in the 18th century and were catalogued so that eyeball observers using small telescopes would not confuse them with comets.
These objects are generally of large angular size and hence larger than the typical field of view of many CCD detector systems; hence CCD images of these objects are somewhat rare compared to photographic ones.
In this resource, we offer CCD images of many of these objects, taken with a variety of different telescopes, along with a description or narration of brief facts about them.
